Solidago plant named ‘Dansolwind’

ABSTRACT

A new and distinct  Solidago  plant named ‘Dansolwind’ particularly characterized by having a plant height of 70-75 cm., small yellow inflorescences, green leaves, a rapid growth cycle and an even growth rate.

Botanical description: Solidago sp.

Variety denomination: ‘Dansolwind’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the goldenrod plant, botanically known as Solidago sp., and hereinafter referred to by the cultivar name ‘Dansolwind’.

Solidago, of the sunflower family, Asteraceae, consists of approximately 100 species of goldenrod plants found in North America, most of which are geographically located in the East. Goldenrods are perennial plants that commonly grow along stream banks, ditches, roadsides and other areas where the soil is moist and rich.

The new Solidago cultivar is a product of a planned breeding program conducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to develop a new Solidago variety with a small yellow inflorescence, green leaves, a rapid growth cycle, and an even growth rate.

The new Solidago cultivar originated from a cross made by a planned breeding program discovered by the inventor in 2000 in Moshav Mishmar Hashiva, Israel. The female parent is designated as ‘1-Y-1’ (unpatented). The male parent is unknown. The new Solidago cultivar ‘Dansolwind’ was selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new Solidago cultivar by leaf cuttings was first performed in October, 2001, in Moshav Mishmar Hashiva, Israel, and has demonstrated that the combination of characteristics as herein disclosed for the new Solidago cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Dansolwind’ which in combination distinguish this Solidago as a new and distinct cultivar:

-   -   1. Small yellow inflorescences;     -   2. 70-75 cm in height;     -   3. Green leaves;     -   4. Rapid growth cycle; and     -   5. Even growth pace.

Plants of ‘Dansolwind’ differ from the plants of the female parent, ‘1-Y-1’ (unpatented) primarily in branch and inflorescence strength. ‘Dansolwind’ has sturdier branches and denser inflorescences than the mother plant.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Dansolwind’ is the Solidago cultivar ‘Tara’ (unpatented). Both cultivars have small yellow inflorescences. However, the inflorescences of ‘Tara’ are a lighter yellow color, most similar to yellow group, RHS 7A, whereas the inflorescences of ‘Dansolwind’ are most similar to yellow group, RHS 13A.

BRIEF DESCRIPTION OF THE DRAWINGS/PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Solidago cultivar ‘Dansolwind’ showing the colors as true as is reasonably possible with colored reproductions of this type. Color in the photographs may differ slightly from the color value cited in the detailed botanical description which accurately describe the color of ‘Dansolwind’.

DETAILED BOTANICAL DESCRIPTION

The new Solidago cultivar ‘Dansolwind’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe the new Solidago cultivar as grown in the field in Moshav Mishmar Hashiva, Israel, under conditions which closely approximate those generally used in commercial practice. The photographs and descriptions were taken during September of 2004, when the outdoor day temperature averaged 30° C. and the outdoor night temperature averaged 24° C. The plant was grown with fertilization N:P205:K20 in the ratio of 5:3:8. The age of plants described is 10 weeks.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 12:00 p.m. in Moshav Mishmar Hashiva, Israel.
